STEAM HEATER.

1 i The Schcdnldrefened to in Ben known; that wanna: o. BAKER, of the city-and State of New-York, have invented an Improvement in Steam Radiators; and the following is declared to ber'a correct. description thereof. V

Theobject of this invention isito support the thin sheet metal used for the radiators, without the use of numerous rivets or stayspassing across the steam -spaces,andrendering'thesheet metalliabletobecom'e rustyor leaky; furthermore, to-u increase the area of the'radiating surface without increasing the external size of the apparatus, and todnsure a circulation of the steanifand thedeliver ypf the water of 00116611831 v tion, and any air or gasesyfrom the apparatus under circumstancesthatpreclude the possibility ofthe parts 1 I. make uselofflat shest-metal radiators, opening h ainhcr, the other end being ision in each radiator that closedyand there 'tdtjh'e" steam-inlet, so thatit will-not he liable'to freeze, asis the case frequently in cold weather on starting the apparatus, where the delivery-pipe is at a distance from the steam-supply pipe.

I, The flat radiators are supported by intervening corrugated stays, and 'tbese infi turn ultimately are sns:

tained by. the inclosing-case of the apparatus, so that the support. for the radiating-chambers is external, rendering the nee of intersecting rivets and braces In thei drawing is a sectional plan of partof the appa rams l l The radiatorscarewmadein a; flatflform, of sheet metal; and extend from one or" two sides of the ch'ame her a. I have} shown them asjextending from opposite 1 sides ot saidchamherl l a I e Thesearadiators should lieplaced side by sideythe spaces between the radiators beingabout the same as fthat ot the radiatorsthemselves; but I do not limit myselfin thisparticnlar; 1

Eacli radiator is madeiwith one end firmly attached to? tlie chamber audit other end closed.

There is a division, 2,-in each radiator, and the opening or openiugsfrom the chamber a. into the' radiator are abovefithis division, as; at 3: 32'

theseLettern Patent part of the same The division 2 descends near its outer end at 4, and

there is an opening, 5, from the radiator into the space 1 helowthe division e in the chamber a.

' This construction insures a circulation of the steam,

from the chamber a,'th r ough the radiators,and the. watercf condensation returns beneath the division e,

and runs back into the boiler through .the lower part of the steam-pipe,

v The divisions 2 become stays or supports, to" prej vent the chamberscollapsing, and it will be evident j-that more than one division or stay may be provided in each chamber. It'is to be'un'derstood that this radiator isplaced at a higher level than the boiler, as'usnal, so that there 1 ma bea descent in the steam-pipe from the radiator .becominginjured, especially from.frost, when the ap-g i .paratuls is being heated pp, orwhen it has been left exposed to'the cold. a a

to the boiler. I v Byemploying only one pipefor both steam and water, the connection between the radiating apparatus 1 and boiler is rendered more simple than heretofore,

and there is no risk of the water of condensation freez- 8 ing in its'return to the boiler. insures thecirculationof steam and the-driving out wof'atmosphericai-rt. The water of; condensation is taken away adjacent The steam radiating-chambers, made as aforesaid,

i may be used with any desired connection to the boiler.

The steam, as it fills the apparatus, rises tothe top,

and displaces theair; hence the air is gradually driven do vn, and'passes off by a pipe, at h, that may baled to the ash-pit of the furnace or any other convenient place. This pipe. maybe left open, to allow air to escape or air-to enter the apparatus, and prevent col-' lapsing.

, The'pipe h is to rise above the overflowforwater,

to prevent water entering the same.

The spaces between the respective radiating cliamtbers receive the corrugated stays I, that are made of metallic plates, bent. or corrugated, so as toclosely fill the space between the chambers and-sustain thesheet metal of such chambers against -;thepressure of the steam, and at the sametime form radiating surfaces to warmthe I air, that has a free circulation through a a \thecorrugations of said plates.

Y The steamchambera-is made with a. pipe,'l1,-connect ed at one side,and through: which steam passes intothe apparatus. a r

The outer casing M of the radiator is lined with metal, and braced by the stays a and bolts t, so as to 3 support the. same firmly against the pressure of steam acting upon the corrugated stays-Z, through the plates of theradiators'.

Thensual openings are providedin the lower part of the case, for admitting atmosphere, and in the up er'part' for the warm air to pass into the building. 3

It is'to be understood that this casing m, being made complete, sppp'ort-s theradiating-cha mbers, and

ported withconvenien cefrom the that it canbe l manufact'ory to" thelp'lace of use, and only requires to be suspended from the ceiling in the cellar, insteadof being onlyan inclosure, as heretofore made ontthe' premises, that did not aid in strengthening the radi ator. V

I claim as my invention- 1. The flat sheet-metal radiating chambers, with separateintermediate external stays 0r supports, forming also radiators, the parts being confined hy tiehoits that do not pass through the steam-spaces, sub stantially as specified.

2. The sheet-metal steam-radiators, made with the divisions 2, steam-inlets 3, and outlet 5, so as to produce a circulation, as specified.

3. The division e of the steam-chamber, separating the steam and waterof condensation, in combination Witnesses:
